Process Description
Raw Material Preparation
Rice flour is prepared under controlled hygienic conditions and mixed with purified process water to form a homogeneous slurry.
Enzymatic Hydrolysis
Food-grade enzymes selectively hydrolyze starch while preserving protein integrity.
Advantages include:
- High protein recovery
- Excellent digestibility
- Mild processing conditions
- Reduced protein denaturation
- Improved functionality
Protein Separation
Advanced centrifugation systems efficiently separate protein-rich fractions from hydrolyzed starch.
Recovered starch can be further processed into valuable co-products.
Membrane Filtration
Ultrafiltration and diafiltration systems concentrate proteins while removing:
- Sugars
- Minerals
- Low molecular weight compounds
- Process water
Benefits include:
- Higher protein purity
- Reduced water consumption
- Consistent quality
- Improved processing efficiency
Protein Concentration
The purified protein concentrate is standardized before downstream processing.
Continuous monitoring ensures excellent batch consistency.
Homogenization & Pasteurization
The protein slurry undergoes homogenization followed by pasteurization to improve stability and ensure microbiological safety.
Spray Drying
Advanced spray drying technology converts the slurry into premium-quality free-flowing powder with:
- Excellent dispersibility
- Neutral taste
- Low moisture
- Long shelf life
Quality Standardization
Each production batch is analyzed for:
